From September to about a week ago, there was an exploit that allowed private information transmitted via the Cloudflare proxy service network to be seen by others, including login info. FA uses Cloudflare, so it might be a good idea for everyone to change their passwords, just in case they may have been compromised. (Yes, I know... "Who cares what a bunch of furry freaks are doing?" Consider, though, how often people reuse passwords over multiple sites because it's less hassle than messing around with a PW manager or remembering a buttload of different passwords.) More information about the issue can be found here, including a ~21MB text file with a complete list of domains that may have been affected by the exploit, and Cloudflare's own discussion of the issue can be found here.
